Studies on the DC 6 were started during World War Two to meet the US Air Forces demands for long-range military cargo planes. It was converted for civilian transport immediately after the war and equipped with a pressurized cabin and the means to carry 52 to 68 passengers. UNITED AIRLINES was the first company to receive the DC 6 in April 1947. It was a DC 6B flown by S.A.S. which made the first transpolar flight from LOS ANGELES to COPENHAGEN in 1952.
288 DC 6Bs were built until production stopped in 1958.
